Check out the Lincoln Mig Pac 10 and 15 units at Eastwood. These are great
for body work and the 15 can weld some serious metal. They come with a
conversion kit on sale Mig Pac 10 $435/ Mig Pac 15 $575. I have used the
MIG PA 15 extensively on a Morris Minor restoration. You can really weld
thin material with these units.
The SP-100 is the basic flux core welder that Lincoln sells to get you into
the MIG market. It does not have the circuitry to control the welding that
the MIG PAC version can do. Check out the details on Eastwood's site
